A single resistor is connected in circuit. A 2 A of current is flowing through circuit and potential difference across resistor is 12 Volts. The value of the resistor is:
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.
For the circuit shown in the diagram below:
What is the value of: (i) current through 6Ω resistor? (ii) potential difference across 12Ω resistor?
