A resistor of 6 Ω is connected in series with another resistor of 4 Ω. A potential difference of 20 V is applied across the combination. Calculate:
(a) the current in the circuit, and
(b) the potential difference across the 6 Ω resistor.
A resistance 2Ω, 4Ω, 8Ω are connected in series with a resistance of 4Ω and a potential difference of 20Volt is applied. Calculate the current & potential difference across the 6Ω resistors.
