Voltage across capacitor, V = 2.0V
Capacitance of Capacitor, C =
4.0 μF
Charge stored in Capacitor, Q = ?
The capacitance formula, C = Q/V
We can rewrite this as Q = CV
Therefore,
the amount of charge stored in this capacitor = 2.0 * 4.0
μC
= 8.0
μC

Answer:
Q = 8 μC
Step-by-step explanation:
The relation between voltage, capacitance and charge can be expressed using the following rule:
Q = C * V
where:
Q is the amount of charge that we want to calculate
C is the capacitance = 4 * 10⁻⁶ F
V is the voltage applied = 2 V
Substitute with the givens in the above equation to get the amount of charge as follows:
Q = C * V
Q= 4 * 10⁻⁶ * 2
Q = 8 * 10⁻⁶ Coulumb
Q = 8 μC
Hope this helps :)
