79. Ssm consider the circuit in the drawing. Determine (a) the size of the current in the circuit and also (b) the size of the voltage between the points labeling A and also B. (c) State i beg your pardon point, A or B, is in ~ the higher potential. 
Assume the existing goes clockwise.� compose a Kirckhoff loop equation beginning at point A 


Solve for i 



Voltage walk from A to B 


Since going from A to B is a rise of voltage, point B is at higher potential. 

You are watching: Find the magnitude of the current in the circuit. Point B is at higher potential!
