P4.6 Parallel circuits

Question 1

What is the total current equal to in a parallel circuit?

Answer 1

The sum of the currents through the separate branches

Question 2

What is the potential difference in a parallel circuit?

Answer 2

Is the same across all componenets

Question 3

What is the equation to calculate current?

Answer 3

Potential difference / resistance

Question 4

Why does adding more resistors in parallel decreases the total resistance?

Answer 4

Multiple paths for charge to flow in
total current is greater (for the
same potential difference when
more resistors are added)

If current is greater then R = lower because R = V/I
