The figure shows a circuit consisting of a battery and five resistors, with resistances and the battery emf listed below. What is the potential difference across resistor R5? R1 = 6.00 Ω, R2 = 6.00 Ω, R3 = 6.00 Ω, R4 = 4.00 Ω, R5 = 8.00 Ω, and V = 33.0 V.

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
