## 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 Magnetic Force | Nickzom Calculator

The image above represents magnetic force.

To compute the magnetic force of a field, four essential parameters are needed and the parameters are Quantity of Charge (q), Average Velocity of the Charge (v), Magnetic Field Induction or Magnetic Flux Density (B) and Angle between v and B (θ).

The formula for calculating the magnetic force:

F = qVBsinθ

Where;
F = Magnetic Force
q = Quantity of Charge
v = Average Velocity of the Charge
B = Magnetic Field Induction or Magnetic Flux Density
θ = Angle between v and B

Let’s solve an example;
Find the magnetic force of a field when the Quantity of Charge (q) is 11, Average Velocity of the Charge (v) is 20, Magnetic Field Induction or Magnetic Flux Density (B) is 17 and Angle between v and B (θ) is 28°.

This implies that;
q = Quantity of Charge = 11
v = Average Velocity of the Charge = 20
B = Magnetic Field Induction or Magnetic Flux Density = 17
θ = Angle between v and B = 28°

F = qVBsinθ
F = 11 x 20 x 17 x sin28°
F = 11 x 20 x 17 x 0.469
F = 1755.82

Therefore, the magnetic force is 1755.82 Newton (N).
