Parallel Circuits Oh! It’s nice to be together again after a day of work! Let’s have some dinner! Oops!!! Hello my dear! Hello love! See you later, I’m going to work! Bye! I’m going too!
Spot the closed circuits Follow the circuit with your finger and find out where the closed circuits are!!!
Working Not working Draw a closed line around the closed circuits and say if they are working Working
