Study Notes
Charge
- Denoted as Q, it is calculated using the formula Current (I) multiplied by time (t).
Voltage
- Represented as V, calculated by multiplying current (I) with resistance (R): V = I x R.
- Alternatively, voltage can also be determined by dividing energy (E) by current (I): V = E / I.
Power
- Symbolized by P, power can be calculated as the product of voltage (V) and current (I): P = V x I.
- Also expressed as the square of current (I²) multiplied by resistance (R): P = I² x R.
Energy
- Denoted as E, energy is computed using power (P) multiplied by time (t): E = P x t.
- Energy can also be expressed as the product of voltage (V), current (I), and time (t): E = V x I x t.
Series Circuit
- Total resistance in a series circuit is the sum of individual resistances: R_total = R1 + R2 + R3.
Parallel Circuit
- Total resistance in a parallel circuit is found using the reciprocal of the sum of the reciprocals of individual resistances: 1/R_total = 1/R1 + 1/R2 + 1/R3.
