# Faraday’s law equation

Faraday’s law equation.

I’m trying to learn for my Physics class and I’m stuck. Can you help?

1-Write down the Faraday’s law equation. __Name each of the 3 quantities__ of this equation.

2-How much is ε when the magnetic flux does not change?

3-Explain the reason behind the minus sign in this equation.

4-In part 2 of the lab, we are using a coil as an inductor. What is an inductor (i.e. how will it affect the current of the resistor)?

5-What is the time constant (τ) of a circuit that contains an inductor (L) in series with a resistor (R)?
