Question 8 of 10 0.5 Points
A 121 O resistor and a 198 O resistor are both connected in parallel across a power supply. If the potential drop across the 121 O resistor is 14 V, what is the potential drop (in V) across the 198 O resistor?

Explanation / Answer

In the series combination of resistances, current passing through each resistance is same. And the sum of potential drops across each resistor is equal to voltage of the power supply. Therefore, V1 + V2 + V3 = 15 V                    4.1 V + 3.1 V + V3 = 15 V                            V3 = 7.8 V In the series combination of resistances, current passing through each resistance is same. In the series combination of resistances, current passing through each resistance is same. Current passing through the resistance 213 resistance is 0.25 A then the current passing through the resistance 221 is also 0.25 A Please post the remaining questions as separate.
