Two resistors R2 and R3 are connected in parallel, and this combination is connected in series with a third resistor R1. If R2 = 5.0 Ω, R3 = 2.0 Ω, and R1 = 6.0 Ω, How much power is delivered to the 2.0 resistor if the battery potential is 12.0 V?

An alpha particle is moving at a speed of 5.0 × 105 m/s in a direction perpendicular to a uniform magnetic field of strength 0.040 T. The charge on an alpha particle is 3.2 × 10-19 C and its mass is 6.6 × 10-27 kg. What is the radius of the path (in meters) of the alpha particle to two significant digits?

If a cellular membrane has a potential difference of 3.0 mV, how much current in micro-Amps of ionic charge would flow if the resistance of the membrane were a kilo-Ohm?

The potential always drops across a resistor.

A circuit contains a 10.0 , a 9.0 , and a 6.0 resistor. Calculate the minimum amount of resistance in this circuit. Express answer in two significant digits.
