If you want to find Voltage in Volts:
V = IR
Given: I= 2 Amps and R = 5 Ohms
V=10 Volts
V=7 Volts
V=3 Volts
V=8 Volts
If you want to find Resistance in Ohm’s:
R = V / I
Given: V = 9 Volts and I = 4 A
R= 2.25 Ohms
R=13 Ohms
R=5 Ohms
R=14 Ohms
If you want to find Current in Amps:
I = V / R
Given: V= 140 V and R = 2Ω
I= 142 Amps
I= 138 Amps
I= 70 Amps
I=72 Amps
When do you consider repairing electrical wirings at home?
