What is the formula for Ohm's Law?

V = I * R

R = V - I

I = V + R

V = R / I

Define voltage and its unit of measurement.

Voltage is the electric potential difference measured in volts (V).

Voltage is the measure of current in amperes (A).

Voltage is the resistance measured in ohms (Ω).

Voltage is the power measured in watts (W).

What is the relationship between current, voltage, and resistance?

Voltage (V) = Resistance (R) / Current (I)

Current (I) = Voltage (V) + Resistance (R)

Resistance (R) = Voltage (V) - Current (I)

Voltage (V) = Current (I) x Resistance (R)

Explain the difference between series and parallel circuits.

Series circuits can have multiple paths for current.

In series circuits, the voltage is divided among components.

Series circuits have a single path for current, while parallel circuits have multiple paths.

Parallel circuits have a single path for current.

How do you calculate total resistance in a series circuit?

R_total = R1 / R2 / R3 / ... / Rn

R_total = R1 + R2 + R3 + ... + Rn

R_total = R1 * R2 * R3 * ... * Rn

R_total = R1 - R2 - R3 - ... - Rn
