Answer 1

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\purple{R}}}}$

Ohm's Law and Resistance. Ohm's law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm's law is V=IR.

Answer 2

Explanation:

Ohm's law states that Current through a conductor is directly proportional to voltage difference across it. ... The circuit diagram to verify ohm's law is drawn below. Voltmeter across a resistor is connected in parallel. Ammeter to measure current in the circuit is attached in series. A variable resistor is connected.

Ohms Law and Power

1. [ V = I x R ] V (volts) = I (amps) x R (Ω)

2. [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)

3. [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)

4. It is sometimes easier to remember this Ohms law relationship by using pictures.
