Question

Q1. Three resistors of resistances 1.2 1, 31 and 1.8 are
connected in series across a battery of 1.2V. Draw the circuit
diagram, find the equivalent resistance and voltage across each
resistor​

Answer 1

Answer:

Explanation:

Since the three resistances are in series the equivalent resistance = sum of all three resistances.

The voltage across each resistor will be in the same ratio of the resistors themselves and the sum of voltages will be equal to 1.2 V

$R_{total} = r1 +r2+r3\\v1:v2:v3 = r1:r2:r3\\\\So \\v1 = V*r1/R_{total} \,\,\,\,\,\,\, (V = 1.2V)\\and\, so \,on...$
