Question

how much current is flowing through a 3k resistor when a potential difference of 6v is applied across its ends?......

Answer 1

Current = Potential difference / Resistance
Current = 6/3
Current = 2 Ampere
Hope it helps......

Answer 2

resistor , R= 3 ohm
potential difference ,V = 6V

potential difference = current × resistor
6 = current × 3
current = 2 Ampere
