Share:
- 1The voltage drop across the series component reduces to half of its initial value
- 2The voltage drop across the series component increases to the total source voltage✓
- 3The voltage drop across the series component remains unchanged
- 4The voltage drop across the series component decreases to zero
Correct answer
The voltage drop across the series component increases to the total source voltage
