What is the current when the voltage is 18 volts and the resistance is 6 ohms?
What is the current when the voltage is 18 volts and the resistance is 6 ohms? 108 amps.
How do you calculate amps with volts and ohms?
Ohms Law and Power
- To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
- To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
- To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)
- To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)

How many volts is a 20-amp circuit?
What happens if you put a 20 amp breaker on 14 gauge wire?
6 Answers. I would say 14 gauge wire anywhere on a 20 amp circuit is not OK. The purpose of the breaker is to cut off power before the wiring overheats. If you plug in several devices on an outlet that total 20 amps, you will exceed the safe working capacity of the 14 gauge wire without tripping the breaker.
Can I mix 12 gauge and 14 gauge wire?
mixing 14-gauge NM and 12-gauge. both 14 and 12 gauge will be protected by a 15A breaker. Code states that 14Ga will be protected by an overcurrent device of not more than 15A and 12GA by 20A. 14 and 12 are both ok behind a 15amp breaker, but you must use one or the other and not both.
