Question

plz give me some problems on resistance for class 10(tough)

Answer 1

Hi Friend,

1.Find the total resistance of eight resistors below:
R1 = 10 Ω 
R2 = 2 Ω 
R3 = 3 Ω 
R4 = 17 Ω 
R5 = 20 Ω 
R6 = 20 Ω 
R7 = 8 Ω 
R8 = 10 Ω 

2. 8 resistors, each having a resistance of 10 Ω?
Find the total resistance!

3.A power saw at the local hardware store boasts of having a 15-Amp motor. Determine its resistance when plugged into a 110-Volt outlet.

4.An overhead high voltage (4.0x105 V) power transmission line delivers electrical energy from a generating station to a substation at a rate of 1500 MW (1.5x109 W). Determine the resistance of and the current in the cables.

5.The UL panel on the bottom of an electric toaster oven indicates that it operates at 1500 W on a 110 V circuit. Determine the electrical resistance of the toaster oven.

6.A 9.00-volt battery is used to power a series circuit with a 2.50 Ω and a 3.50 Ω resistor. Determine the power rating of each resistor and the total power of the circuit

7.Determine the equivalent resistance of a parallel arrangement of two resistors with resistance values of …
a. … 8.0 Ω and 8.0 Ω
b. … 5.0 Ω and 5.0 Ω
c. … 5.0 Ω and 8.0 Ω
d. … 5.0 Ω and 9.2 Ω

8.A 9.00-volt battery is used to power a parallel circuit with a 2.50 Ω and a 3.50 Ω resistor. Determine the power rating of each resistor and the total power of the circuit.

9.A circuit powered by a 12.0-volt battery is comprised of three identical resistors in series. An ammeter reading reveals a current of 0.360 A. Determine the resistance values of the resistors and the voltage drops across the resistors.

10.The UL panel on the bottom of an electric toaster oven indicates that it operates at 1500 W on a 110 V circuit. Determine the electrical resistance of the toaster oven.
