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, R2and R3have 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

Explanation:

A straight line plot shows that as the current through a wire increases, the potential difference across the wire increases linearly – this is Ohm's law. ... (12.7) that the current through a resistor is inversely proportional to its resistance. If the resistance is doubled the current gets halved.
