How to Calculate and Solve for Capacitance | Electrical Properties

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.

How to Calculate and Solve for Electric Field Intensity | Electrical Properties

The electric field intensity is illustrated by the image below.

To compute for electric field intensity, two essential parameters are needed and these parameters are Voltage (V) and Distance between Plates (l).

The formula for calculating electric field intensity:

E = V / l

Where:

E = Electric Field Intensity
V = Voltage
l = Distance between Plates

Let’s solve an example;
Find the electric field intensity when the voltage is 24 and the distance between plates is 8.

This implies that;

V = Voltage = 24
l = Distance between Plates = 8

E = V / l
E = 24 / 8
E = 3

Therefore, the electric field intensity is 3 Vm-1.

Calculating the Voltage when the Electric Field Intensity and the Distance between Plates is Given.

V = El

Where;

V = Voltage
E = Electric Field Intensity
l = Distance betweeen Plates

Let’s solve an example;
Find the voltage when the electric field intensity is 10 and the distance between plates is 5.

This implies that;

E = Electric Field Intensity = 10
l = Distance between Plates = 5

V = El
V = 10 x 5
V = 50

Therefore, the voltage is 50 V.

How to Calculate and Solve for Resistance | Electric Resistivity

The resistance is illustrated by the image below.

To compute for resistance, two essential parameters are needed and these parameters are Voltage (V) and Current (I).

The formula for calculating resistance:

R = V / I

Where:

R = Resistance
V = Voltage
I = Current

Let’s solve an example;
Find the resistance when the voltage is 22 and the current is 11.

This implies that;

V = Voltage = 22
I = Current = 11

R = V / I
R = 22 / 11
R = 2

Therefore, the resistance is 2Ω.

How to Calculate and Solve for Current | Ohm’s Law

The current is illustrated by the image below.

To compute for current, two essential parameters are needed and these parameters are Voltage (I) and Resistance (R).

The formula for calculating current:

I = V / R

Where:

I = Current
V = Voltage
R = Resistance

Let’s solve an example;
Find the current when the voltage is 21 and the resistance is 7.

This implies that;

V = Voltage = 21
R = Resistance = 7

I = V / R
I = 21 / 7
I = 3

Therefore, the current is 3 A.
