What is the nature of load connected across dc motor?
heavy load
A coil of 8 ohm parallel with coil of 20 ohm This is connected in series with 12 ohm resistor If the whole circuit is connected across a battery having emf of 30V internal resistance of 2ohm whats v?
v of what? v across what? v measured from what 2 points? v across the coils? v across the resistor? v across the coils and resistor? v across the battery? v across the battery and coils? v across the battery and resistor? or are you asking what v stands for? v stands for voltage.
What is the amount of power consumed by a 60 watt 220 volt lamp when it is connected across 110 volt supply?
What is the amount of power consumed by a 60 watt 220 volt lamp when it is connected across 110 volt supply?
Are two toy electric trains running on the same track connected in series or parallel?
Two toy electric trains running on the same track are connected in parallel because they both get energized from DC impressed across the two rails they ride on.
What will happen to the electric pressure differences across the battery terminals when a second long bulb is added in parallel to a single long bulb connected to a fresh battery?
there will be little or no change
At what condition the voltmeter connected across the wheatstone bridge will be zero?

How is the power factor meter connected?
power factor meters are connected across the supply
How do you connect an ammeter and voltmeter?

How a electric heater works 2 references?
An electric heater is a resistor that dissipates electric power when a voltage is connected across it and a current flows through it. The amount of power in watts is equal to the voltage times the current in amps. Typical space heaters for use in the home are 1.5 kW to 3 kW to heat a single room.
How come birds on electric wires dont get electrocuted?
For an electric current to pass through the bird's body, there must be a potential difference (voltage) across its legs. But its legs are connected to a very good conductor which means that the bird's legs must be at the same potential -no potential difference, no shock!
How do electric generators convert kinetic energy into electrical energy?
They revolve sets of coils of wire across a strong magnetic field, and this induces electrical currents in the coils. NB The current will only flow if thetwo ends of the coils are connected, and this is achieved by whatever circuit is connected to the generator's output.
Voltmeter is connected in parallel with resistor?
A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.
To measure voltage drop across a component or connector the voltmeter must be connected in?
it must be connected in parallel as always
