- the voltage is the same across each resistor. 17 Essay 1 point A plane mirror stands vertically on a table. A ruler lies on the table in such a position as to make an angle of \( 30^{\circ} \) with the mirror. Determine the angle between the ruler and its image.

A 30W light bulb and a 60W light bulb are connected in series with a 6-volt battery: a) What is the current in each bulb? b) What is the voltage across each bulb? c) What is the power dissipated by each bulb? d) What is the total power dissipated by the wire? Four identical resistors connected in parallel have an equivalent resistance of 2 ohms. What would the total resistance be if these resistors are then connected in series? Four resistors and a battery of negligible internal resistance are assembled to make the circuit in the figure. Let ε = 4.5V, R1 = 20Ω, R2 = 30Ω, R3 = 90Ω, and R4 = 10Ω. Find: a) the equivalent resistance of the network; b) the current in each resistor. R2 R3 Five resistors are connected in a series-parallel combination as shown: Find the following: a) the total resistance of the circuit; b) The total current in the circuit; c) the current in the 100Ω resistor; d) the voltage drop across the 80Ω resistor. 400Ω 600Ω 800Ω 1200Ω 1000Ω 20Ω
