Find the Total Resistance in the circuit if all the 8 resistances are equal to 36Ω and total voltage of the battery is 36 volts.

A resistor made out of gold (conductivity = 4.1.107 ) has a cross section with area A = 2mm² and length 1 = 40mm.

Answer the question   Plot the current- voltage relationship for a four-band resistor with the color code Gray, red, black, red, gold?  If you wish to increase the amount of current in a resistor from 100mA to 150mA by changing The 20V source, by how many volts should you changes the source? To what new value should You set it  The potentiometer connected as a rheostat in given circuit is used to control the current to a heating element. When the rheostat is adjusted to a value of 16 ohm or less, the heating element can burn out. What is the rated value of the fuse needed to protect the circuit if the voltage Across the heating element at the point of maximum current are 200 V and the voltage across The rheostat is the difference between the heating element voltage and the source voltage? (Vin =220v)

Question 11 What is the voltage and current at location A with (1) the switch open and (2) the switch closed in terms of voltage V and resistance R A + + V V R R R R
