Phys 165 Module 8 Exam
A 20-Ω and 10-Ω resistor are stressed out in collection. Calculate the equivalent resistance. -
ANS-Use Rt= R1+R2
Rt= 20 + 10 = 30
*30 Ohms*
A five.00-Ω and 11.0-Ω resistor are stressed out in parallel. Calculate the equivalent resistance.
- ANS-(1/R)=(1/R1)+(1/R2)
So(1/R)=(1/five.00)+(1/11.Zero)
1/.29 for RT
*3.45 ohms*
A 6.Zero-volt battery is hooked up in a circuit with a four.Zero-ohm resistor. Find the current via
the circuit. Show your work. - ANS-V= 6 R= 4
Use ΔV = IR I= V/R
I= 6.0/ four.Zero
I= *1.5 amps*
An electronic tool uses a circuit with a 20.0-ohm resistor. If the present day thru the circuit is
four.00 amps, how a good deal power is used by the device? - ANS-P=I^2R Answer in Watts
P= four^2 x 20.0
*P = 320 W*
Figure eight.T.2 suggests a part of a circuit that incorporates 4 resistors with resistance as
shown within the parent. Calculate the subsequent values:
A. Calculate the equivalent resistance of the ninety five- and 35- resistors.
B. Calculate the equivalent resistance of the 25-, ninety five-, and 35- resistors.
C. Calculate the equal resistance of the entire circuit. - ANS-A) 1/Rt= 1/R1+1/R2
1/Rt= 1/ 95 + 1/35 = 2.56
*2.56 Ohms*
B) Rt= R1+R2
2.Fifty six + 25 = *27.56 Ohms*
C) 1/Rt= 1/R1 + 1/R2
1/x for Rt. Answer in Ohms
For a set of resistors that are connected in *parallel*, which of the subsequent statements is
authentic? Assume that the resistance of each resistor is exceptional.
A) The sum of the current via every resistor is same to the entire present day of the circuit.
B) The equal resistance is same to the sum of the person resistances.
C) The overall voltage of the circuit is identical to the sum of the voltages across every resistor.
D) A, B, and C are genuine. - ANS-A) The sum of the contemporary thru every resistor is same
to the full present day of the circuit.
