If the loads are wired in series, add the three values to get the total R.
If they are in parallel then the formula is 1/R = 1/R1 + 1/R2 + 1/R3
The total resistane when resistors are in parallel is ALWAYS LESS than the lowest individual value.

How do you calculate the electromotive force required to push 5 amperes through 22 ohms resistance?
Ok so if you have to take the 5 amperes and multuply them by the 22 ohm resistance giving you the answer of 110 5 * 22 = 110 volts
How do you calculate the current taken on 230 volts for a resistance load that takes 5 amps on 110 volts?
We can do this by using Ohm's Law: V = I x R, where V is the voltage, I is the current and R is the resistance. Re-arranging Ohm's Law, R = V / I so 110 / 5 = 22 ohms. Again re-arranging Ohm's Law, I = V / R so 230 / 22 = 10.45 amps.
A 22 k and Ohm and 12 k and Ohm resistor are connected in series across a 68 V source how is the voltage divided?
If the resistors are in series the voltage can not be divided, as it has to pass first through one then the other. The amount of current that flows through a set of resistors in series will be the same at all points and the total resistance in the circuit must be equal to the sum of all the individual resistors added together. In other words the 22k and 12k Ohm resistors are the sames as a single 34k Ohm resistor.
How sensitive is 22k resistor?
"Sensitivity" is not a word normally applied to resistors. Characteristics of resistors include "resistance", "tolerance", "power rating", and "temperature coefficient". "Inductance" and "capacitance" are also used in describing certain critical performance resistors. A 22 KOhm resistor will require 22 v of voltage to induce a current of 1 ma. This is Ohm's Law: voltage = current times resistance.
What is 22 percent of 15?
15% of 22= 15% * 22= 0.15 * 22= 3.3
How do you charge an 8 volt battery with a 12 volt charger?
You can do it by putting a resistor in series to limit the current, but you have to calculator the resistance needed. First you need to find out the capacity of the battery, e.g. 2000 mAh (milliamp-hours). The charging current should be set at at one tenth the capacity (or less). So in the example, the charging current is 200 mA, or 0.2 amp. The resistance is found by dividing the voltage drop, four volts, by the current. That gives a resistance of 4/0.2 or 20 ohms. You can use a 22-ohm resistor. It dissipates a power of 4 x 0.2 watts, or 0.8 watts, so it should be a 22-ohm 1 watt resistor.
What is a estimate of 15 percent of 22?
15% of 22 = 15% * 22 = 0.15 * 22 = 3.3
What is 22 divided by 15?
1.4667
What is the resistance of the AC electric Bulb in which current is 10 ampires when the potential difference is the 220 volts in your home?
The relationship between Volts, Amps and resistance is expressed by the following formulas. V = A*R, A = V/R, R = V/A, So to calculate the resistance of the lightbulb use R=220/10. Resistance equals 22 ohms. If you were to measure the resistance of the bulb with an ohm-meter you would get a lower reading. The resistance of the filement goes up as the bulb heats up. So the current (amps) are higher than 10 amps when the bulb is first turned on.
What is 15 percent of GBP 22?
15 % of £22 = 15/100 × £22 = £3.30
