The terminal voltage of a battery depends on the electromotive force of the batt

Question

The terminal voltage of a battery depends on the electromotive force of the battery depends on the internal resistance of the battery depends on the current drawn from the battery all of the preceding (a) and (b) but not (c) The proper relation among I, V, and R for a resistor is: I =VR R = IV V = R/I V = IR R = I/V The total resistance of two resistors depends upon how they are connected. The smaller value of the total resistance occurs when the two are connected: in parallel in series Either of the first two answers may yield a smaller resistance depending on the specific values of the two resistors. There are cases where the total resistance would remain equal, whether the resistors are connected in series or in parallel. Power dissipated though a resistor can be represented by all of the following, EXCEPT: P = VI P = V^2/R P = I^2R there are no exceptions

Explanation / Answer

9. (C).

Terminal voltage = E - Ir

10. (D)   

V = IR. Ohm's law.

11.(a).

In parallel Req =( R1R2)/(R1 + R2 )

12.(d).
