Formulas
Current (I) (amps)
| Parallel | IT = I1 + I2 + I3 |
|
Ohms law |
I = V/R |
| Series |
IT = I1 = I2 = I3 |
| Indivitual current of resistor in seiries |
(Total resistance / individual resistance) x total circuit current |
Voltage (V) (Volts)
| Voltage drop across each resistor | V = I x R |
Power (W) (Watts)
| Power dissipated by a resistor | P = I x V |
| Power dissipated by a resistor | P = I2 x |
| Power dissipated by a resistor | P = V2 / |
Resistance (Ω) (Ohms)
| Resistance with multiple resistors (Parallel) | Ω = (R1-1 + R2-1 + R3-1) -1 |
| Resistance with multiple resistors (Seiries) | Ω = R1 + R2 + R3 |
| Ohms law | Ω = V / I |
