If it takes 1 minute for 45C of charge to pass a point in an electric circuit, what is the current through the circuit?

Sure, here is the step by step solution:

Step 1: Understand the problem The problem is asking for the current in the circuit. We know that current (I) is the rate of flow of charge (Q) through a point in a circuit over time (t). This is given by the formula I = Q/t.

Step 2: Identify the given values From the problem, we know that:

• The charge (Q) is 45 Coulombs (C)
• The time (t) is 1 minute. But we need to convert this to seconds because the standard unit of time in this context is seconds. So, t = 1 minute * 60 seconds/minute = 60 seconds.

Step 3: Substitute the values into the formula Now we can substitute the values into the formula: I = Q/t = 45C/60s

Step 4: Calculate the current So, the current (I) is 45C/60s = 0.75 Amperes (A).

So, the current through the circuit is 0.75 A.
