Question

(a) Name the law which relates the current in a conductor and the potential

difference across it?

(b) State the above law and express it mathematically.

(c) Three resistors R1, R2 and R3 have the values 5 Ω, 10 Ω, 30 Ω, respectively

are connected in parallel which have been connected to a battery of 12 V.

Calculate (i) the current through 10 Ω resistor,

(ii) the total circuit resistance.

(iii) total current in the circuit.​

Answer 1

Answer:

ohm's law

Explanation:

Ohm's law states the relationship between electric current and potential difference. The current that flows through most conductors is directly proportional to the voltage applied to it.

Answer 2

Answer:

the total circuit resistance
