If two 4 ohm resistors are connected in series which are powered by 240 volts power source, what is the current flow across one 4 ohm resistor?
A
30 amperes
Explaination
Total resistance of the circuit = 4 + 4 = 8 ohms Current flow in the circuit = 240 /8 = 30 amperes In series circuit flow in the circuit elements is same. so 30 amperes current will flow in both series resistors.
