A potential divider is used to give outputs of 4 V and 8 V from a 12 V source. Which combination of resistances, (R 1 , R 2 , R 3 ) gives the correct voltages ? R 1 : R 2 : R 3
Text Solution
Verified by ExpertsThe correct answer is:
B
Resistors are connected in series. So current through each resistor will be same
So,
