The image of capacitance is shown below.
To compute for capacitance, two essential parameters are needed and these parameters are Charge (Q) and Voltage (V).
The formula for calculating capacitance:
C = Q / V
Where;
C = Capacitance
Q = Charge
V = Voltage
Let’s solve an example;
Find the capacitance when the charge is 12 and the voltage is 6.
This implies that;
Q = Charge = 12
V = Voltage = 6
C = Q / V
C = 12 / 6
C = 2
Therefore, the capacitance is 2 farad.
Calculating the Charge when the Capacitance and the Voltage is Given.
Q = CV
Where;
Q = Charge
C = Capacitance
V = Voltage
Let’s solve an example;
Find the charge when the capacitance is 10 and the voltage is 5.
This implies that;
C = Capacitance = 10
V = Voltage = 5
Q = CV
Q = 10(5)
Q = 50
Therefore, the charge is 50.
