Two series 1 k Ohm resistors are connected in parallel with a 2.2 k Ohm resistor

Question

Two series 1 k Ohm resistors are connected in parallel with a 2.2 k Ohm resistor. If the voltage across one of the 1 k Ohm resistors is 6 V. what is the voltage across the 2.2 k Ohm resistor? 13.2 V 12 V 6 V 3 V Power in a series-parallel resistor circuit is dissipated as: resistance change. voltage loss. current flow. heat. If a fifth 10 k Ohm resistor is connected in series in Figure 6-3. how does V_R 4 change? V_R 4 increases. V_R 4 remains the same. V_R 4 decreases. V_R 4 increases to 10 V. R_1 is in series with R_03 in Figure 6-1. True False If R_4 shorts in Figure 6-2. V_R 5 increases decreases remains the same decreases to zero

Explanation / Answer

6) B-----12 voltage

since, if voltage across 1K ohm resistor is 6v then total voltage across series combination is 12V because the current is constant in 1K ohm resistor. 2.2K ohm resistor is connected in parallel to this, in parallel voltage is constant. so, voltage across 2.2K ohm resistor is 12V

7) D---- heat

8) C

9) FALSE, the parallel combination of R2,R3 is in series with R1

10)B---- decreases
