Assignment: Resistive Circuits

problem 1: What are the significant differences in the way ammeters and voltmeters are connected. If an ammeter reads 2.5 A for a period of 4 minutes, determine the charge that has passed through the ammeter. 

problem 2: find out the value of resistor x and the current passing through it.

problem 3: An electric heater is connected to a constant 250 V voltage source and absorbs 1000 W. The heater is subsequently connected to a 210 V voltage source. What is the resistance of the heater? What power does the heater absorb from the 210 V source?

problem 4: Find the power supplied by the voltage source and the power absorbed by the 24 Ω resistor (R3) in the circuit shown below:

problem 5: Determine the voltage V₂ in the circuit shown.

problem 6: For the circuit shown, covert the star into a delta. Draw a diagram of the new resistor arrangement and label the three resistances.

problem 7: Use the loop analysis method to find the current in the 2 k? resistor in this circuit.

problem 8.  Find the power dissipated in the 3 ? resistor in the circuit below using the nodal analysis method.
