Question 1
What is the formula to calculate total current in a parallel circuit?
- I_total = I_1 + I_2 + I_3
- I_total = V / R
- I_total = R_eq / V
π‘ Hint: Think about adding flows together.
Question 2

Question 1
You have a 9V battery connected to two parallel branches, each with a 220 Ξ© resistor. If the second branch is replaced with a 110 Ξ© resistor, what is the new equivalent resistance?
π‘ Hint: Use the parallel resistor formula.
Question 2
In a parallel circuit with four branches (220 Ξ©, 220 Ξ©, 100 Ξ©, and a 330 Ξ© resistor), calculate total current when powered by a 9V battery.
π‘ Hint: Calculate equivalent resistance first.
