Shortcut Formulas in Current Electricity
Ohm's Law
Ohm's Law is one of the most fundamental laws in current electricity that relates the current flowing through a conductor to the voltage applied across it and the resistance of the conductor. The formula is:
V=IR
- V represents voltage (measured in volts)
- I represents current (measured in amperes)
- R represents resistance (measured in ohms)
This formula is used to calculate any of the three variables if the other two are known.
Power Formula
The Power formula is used to calculate the amount of power dissipated by a resistor or consumed by an electrical device. The formula is:
P=IV
- P represents power (measured in watts)
- I represents current (measured in amperes)
- V represents voltage (measured in volts)
This formula is used to calculate the power consumed by an electrical device or dissipated by a resistor when the current and voltage are known.
Series and Parallel Resistance Formulas
The total resistance of a series circuit can be calculated by adding up the individual resistances. The formula is:
RT= R1 + R2 + R3 + ... + Rn
where RT is the total resistance and R1, R2, R3, ... , Rn are the individual resistances.
The total resistance of a parallel circuit can be calculated using the following formula:
1/RT = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn
where RT is the total resistance and R1, R2, R3, ... , Rn are the individual resistances.
Current Divider Rule
The current divider rule is used to determine the amount of current flowing through each branch of a parallel circuit. The formula is:
IRn = (RT/Rn) * IT
where IRn is the current flowing through the n-th branch, RT is the total resistance of the circuit, Rn is the resistance of the n-th branch, and IT is the total current flowing through the circuit.
Voltage Divider Rule
The voltage divider rule is used to determine the voltage across each resistor in a series circuit. The formula is:
VRn = (Rn/RT) * VT
where
