If the current is 5 amps, the resistance = 10 ohms, then what is the potential difference between 2 points in el.circuit in volts?
You already have the formula to solve the question.
V = IR, where Potential Difference(V) = Current (I) * Resistance(R)
your current (I) = 5 amps
Resisrance(R) = 10 ohms, so
V= I*R= 5 amps*10 ohms=50 volts.
