Question

PH 1200 Current and Voltage Summary Current and Voltage - Summary Electric Current 1. Electric current is the flow of charge. The current in a typical toaster is 5A. How electrons? Show your work much charge flows through the toaster in 2 minutes? How many Conservation of Current You should have observed today that current is the same everywhere in a simple circuit. In other words, the current is not "used up" in a toaster when you make toast. Current flows through a toaster: the current in equals the current out. The idea is the same for a junction of wires: the current in equals the current ou 2A 1A + L 2a. What is the magnitude of the current at point X in the figure at right? 2b. What is the current through the battery? Current Measurement 3. Why should you never hook an ammeter directly to a battery?

Explanation / Answer

Q:1

Q = It = 5 A ( 2 x 60 ) = 600 C

no. of electrons= 600/ 1.6 x 10^-19 = 375 x 10^ 19

Q: 2

Point x=3 A

Battery = 3 A

Q: 3 Ammeter are components with very little resistance, if connected directly to voltage source, they will let large current pass through it..which might damage the ammeter
