A 40 W light bulb is connected to a standard wall socket but the voltage is for some reason 330 V. The light bulb is considered to have only resistive resistance, ie current and voltage can be assumed to be in phase. a) Determine the peak value of the current b) Determine the peak value of the voltage c) What is the resistance of the light bulb d) How much energy is generated by the light bulb during 9 minutes

2. a) What is the total resistance of the circuit? b) What is the current through the 100 Ω resistor? c) What is the power dissipated in the 100 Ω resistor? please hand write it or make it very clear to understand

Problem 8:   Consider a circuit shown in the figure. Ignore the internal resistances of the batteries. A) Express the current I1 going through resistor R1 in terms of the currents I2 and I3 going through resistors R2 and R3. Use the direction of the currents as specified in the figure.  B) Write the equation of potential change in loop EBAF in terms of the circuit elements. C) Write the equation of potential change in loop DCAF in terms of the circuit elements.  D) Solve the three equations to get I3 as expression NOT a numerial value
