Electricity Formulas
Few important electricity formulas are given below:
Electric Current (I)
I = Q/t
Where:
- I is the electric current (measured in Amperes, A).
- Q is the charge that passes through a given point.
- t is the time taken.
Electric Charge (Q)
Q = I × t
Where:
- Q is the electric charge (measured in Coulombs, C).
- I is the electric current.
- t is the time taken.
Ohm’s Law
V = IR
Where:
- V is the voltage,
- I is the current,
- R is the resistance.
Power
P = VI
Where:
- P is the power,
- I is the current,
- V is the voltage.
Resistance
R = ρl / A
Where:
- R is the resistance,
- ρ is resistivity,
- l is length, and
- A is area
Watt’s Law
P = I²R or P = V²/R
Where:
- R is the resistance,
- I is Current, and
- V is Voltage
Electric Energy
P = W x T
where:
- P is power,
- W is energy, and
- T is time
Voltage
V = E / Q
where
- E is energy, and
- Q is charge
List of Physics Formulas
Physics is a fundamental branch of science that studies matter, its fundamental constituents, and its motion and behavior through space and time. Physics Formulas are very important during applications of various concepts of physics.
