Question

Draw below a circuit diagram for the circuit in Question 2 with one current sensor hooked up to measure the current in wire A and a voltage sensor hooked up to measure the voltage across the light bulb. Also include a switch in the circuit to turn the bulb on and off. Use correct symbols for all circuit elements. Consider the two circuits below. All bulbs and all batteries are identical. Compare the voltage across the battery in the left circuit to that in the right circuit. Describe the evidence in this lab for your answer.

Explanation / Answer

to proceed with this question, we assume that the current in both the circuits is the same

for the left circuit, the voltage across the battery will be equal to V = IaRa

and for the right circuit, the voltage across the battery will be equal to V = IbRb + IcRc

now since, all the bulbs and batteries are identical, therefore

Vleft = IR

and Vright = I (R+R) = 2IR

so Vright = 2Vleft
