Question

The figure below shows a portion of a circuit. The circuit includes a current sensor (as we are using in lab) and a voltage meter (also as we are using in lab). The voltage meter measures the difference between the red and black leads (V = Vred-Vblack).

When the circuit is turned on the current sensor reads I =-170·mA and the voltage meter reads V = -1.60·V.

(a) Which direction is the current flowing through the circuit element?

     •left
     •right    

(b) Which side of the circuit element is at the higher voltage?

     •right side
     •left side    

(c) Is the current gaining or losing energy as it passing through the circuit element?

     •gaining
     •losing    

(d) Is the circuit element a load or a source of EMF?

     •source of EMF
     •load    

Explanation / Answer

(a)Right

(b)Right

(c)Gaining

(d)Source of emf
