• Miles per hour

Ohm's Law relates which electrical quantities?

• voltage, power, and frequency
• resistance, energy, and capacitance
• current, voltage, and inductance
• voltage, current, and resistance

Which equation represents Ohm's Law?

• V = I + R
• V = I / R
• V = I ^ R
• V = I * R

In a series circuit, the total resistance is equal to:

• the sum of individual resistances
• the average of individual resistances
• the minimum of individual resistances
• the maximum of individual resistances

In a parallel circuit, the total resistance is:(Provide Formula)

• RT = R1 + R2 + R3 + ... + Rn
• RT = R1 * R2 * R3 * ... * Rn
• 1/RT = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn
• RT = R1 - R2 - R3 - ... - Rn
