Answer: 50 V
Explanation:
Given
Three capacitors are connected in parallel across 50 V battery
When capacitor are connected in parallel, net capacitance is the sum of all the values
Net capacitance
[tex]\Rightarrow C=4.7+6.5+15.5\\\Rightarrow C=26.7\ F[/tex]
Voltage in parallel circuit is same across each capacitor. Therefore, voltage across 4.7 F capacitor is 50 V
