Step-by-step explanation:
Current in the circuit is 0.4 A .
Potential drop across 5 Ω resistor is 2 V.
Explanation:
To find :
Current in the circuit.
Potential drop across the 5 Ω resistor.
Given that,
There are three resistors of 5 Ω, 10 Ω and 15 Ω.
Potential drop across the 10 Ω resistor is 4 V.
We know,
Same current flows through all the resistors in series circuit.
We know,
Ohms law,
• V = IR or, I = V/R
[Where, V is voltage, I is current and R is resistance].
Current flowing through 10 Ω resistor :
→ I = 4 V/10 Ω
→ I = 2/5
→ I = 0.4 A
∴ Current in the circuit is 0.4 A .
Now,
Potential drop across the 5 Ω resistor :
→ V = 0.4 A × 5 Ω
→ V = 2 V
∴ Potential drop across 5 Ω resistor is 2 V.

Answer: here sum of all resistance = 5+10+15 = 30
voltage i.e v=15
l = v/r
l = 15/30
l = 1/2 = 0.5 A
