If each resistor represented a light bulb rank each light bulb from brightest on the left to dimmest on the right. 500 50v 2002 1002 250

all resistors have the same value and so do the batteries. Determine the intensity of the current through the resistor R. R= 4Ω V= 4V

Three resistors, R₁ = 232, R₂=3502, and R,=4552, are connected to a capacitor of capacitance C=32μF and a battery with emf 8=14V as shown in the figure below. The capacitor is initially uncharged when the switch is closed at t-0. Determine the current running on R, on the capacitor at r=0. Express your answer in units mA using zero decimal places.

Three resistors are made out of three different materials and Material 1 0.00479 Q-m have different (but uniform) cross sections. Resistor 1 has a Material 2 0.391 Q-m circular cross section of radius 1.18 mm. Resistor 2 has a Material 3 6.87 x 10- 2.m square cross section with a side length of 1.37 mm. The third resistor's cross section is a right triangle with two sides of length 6.47 mm. All of the resistors are 0.838 cm in length. Use the provided table of resistivities to calculate the resistance 3 of each resistor. R1 R2 R3 =
