A 19 V battery delivers 114 mA of current when connected to a 72 resistor. Determine the internal resistance of the battery.?
Internal resistance is approximately equal to 94.667
What circumstances is it possible for the rms current drawn from a certain source to have the same magnitude when an inductance is connected in series with a given impedance?
The same as what? when an inductor is connected in series with a resistor and a current passed through them, the voltages across the resistor and inductor are equal when the reactance is equal to the resistance: 2.pi.f.L = R
The statement that current is equal to the voltage difference divided bythe resistance in known as?
Ohm's Law V = I R Voltage = Current x Resistance
A battery connected to a resistor supplies a current of 4 amps. If another resistor of equal resistance is connected in series with first resistor the current the battery supplies will be how much?
Half that, or 2 amps. The basic rule in circuits is that voltage (E) equals current (I) times resistance (R). Here's how that expression of Ohm's law looks: E= I x R That means that current equals voltage divided by resistance, as is shown here: I = E / R This expression says that resistance is inversely proportional to current (with voltage staying the same). Further, if resistance goes up, current goes down. If resistance doubles (goes up by a factor of 2), which it does in the case specified in the question, then current is cut in half (goes down by a factor of 2). Half of 4 amps is 2 amps, and that's where the answer came from.
What happens to the current in a device if the resistance of the device increases and the voltage difference stays the same?
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
A resistance of produces a current equal to 8 amps when connected th 24 volts?
8
Why is there no flow of electric current between 2 objects of equal resistance?
I am not sure how the two objects of equal resistance are supposed to be connected. But for a current to flow, for example across a resistor, there must be a voltage difference between the terminals of this resistor.

Voltage muiltiplied by resistance measures to current?
No. Voltage divided by resistance is equal to current.

What happens to the current if restistance is increased and why?
There is an electronic formula voltage/resistance = current If you translate this into plumbing terms voltage would equal water pressure resistance would equal pipes and valves and the current would equal the flow rate. If you start closing a valve it increases resistance and lowers the current flow
When two identical cells are connected either in series or parallel across a 2 ohm resistor they send the same current through it calculate the internal resistance of each cell?
as the given cells have the same current flowing in through them (current flowing through the cells connected in series is equal to the current flowing when connected in parallel ) equate the formula's of cells connected in series and cells connected in parallel.thus by equating we get the value of the internal resistor as 2 ohms.
How a transistor transfers resistance?
The input current of transistor is approximately equal to output current .Suppose in common base configuration the emmiter current is approximately equal to collector current if neglect the very small value of bae current.Even though the input resistance is not equal to output resistance,the currents are same ,so we can reliase that the transistor transfers resistance to get same currents at both ends.
The statement that current is equal to the voltage difference divided bythe resistance in known as?
Ohm's Law V = I R Voltage = Current x Resistance
What is the electric current from a battery?
A direct current is obtained from a connection to a battery.

The statement, current is equal to the voltage difference divided by the resistance, is known as?
Ohm's Law. It is usually written as V = I x R or in words Voltage is equal to Current times Resistance; or in your terms I = V / R.
