Question

Two Resistor of 10 ohm and 20 ohm are connected in series to a 3v battery.Find

i) Potential difference across 10 ohm resistor.
​

Answer 1

Answer:

1 VOLT ANSWER

Explanation:

here we have to find. V = ?

for that we find total current across the circuit

using ohm's law V= I.R

V= 3

TOTAL RESISTANCE = 10 + 20 = 30 ( because they are in series )

V = I.R

3 = I . 30

I = 3/30 = 0.1 AMPERE

NOW POTENTIAL DIFFERNCE ACROSS 10 OHM RSISTOR

V. =. I.R

V = 0.1 * 10

V = 1 volt answer
