Part A Determine the equivalent resistance of the circuit shown in the figure. (Figure 1)
Express your answer to three significant figures and include the appropriate units.
Part B
Determine the voltage across 820 Ω resistor.
Express your answer to two significant figures and include the appropriate units.
Part C
Determine the voltage across 960 Ω resistor.
Express your answer to two significant figures and include the appropriate units.
Part D
Determine the voltage across 680 Ω resistor.
Express your answer to two significant figures and include the appropriate units.
820 ohm // 680 ohm , 1/Rp = 1/680 + 1/820
Rp = 371.7 ohm
Rp s eries960 ohm,
so
Req = 371.7 + 960 =1331.7 ohm (ANSWER)
---------------------------------
B) Now using voltage divider ,
V820 = Rp * 12 /(Rp + 960)
V820 = 371.7 * 12/(960 + 371.7)
V820 = 3.35 V is the Volatge acroiss 820 Volts
---------------------------------------------------
C)
Voltage across 960 Ohm = 12 - 3.35 = 8.65 V
--------------------------------------------------
D)
voltage across 680 ohm = voltage across 820 ohm = 3.35 Volts
