An 89 ῼ resistor has a current of 65 mA flowing through it. What is the voltage in the resistor?

Answer :

01-06-2015

Voltage = (current) x (resistance)

65 mA = 65 milliamperes = 0.065 Ampere

Voltage = (0.065 A) x (89 ohms) = 5.785 volts

Voltage is the potential difference between two points.
5.785 is the voltage across the resistor, or between its ends, not 'in' it.
