That is, V (volts) = / (amperes) * A (ohms). What is the resistance of a lightbulb that has a 0.75 amperes current when plugged into 120 volt outlet? Addsional Problem. Appendi >PRACTICE Problems . Soletdom to Selected Problemi Apparedisc For each problem give the rewritten equation you would use and the answer. 1. A lightbulb with a resistance of 50.0 ohms is used in a circuit with a 9.0-volt battery What is the current through the bulb? 2. An object with uniform acceleration a starting from rest, will reach a speed of v in time f according to the formula v = at What is the acceleration of a blcyclist who accelerates from rest to 200 m/s in 4.00 s? 3. How long will it take a scooter accelerating at 0400 m/s' to go from rest to a speed of 4.00 FV'EP 4. The pressure on a surface is equal to the force divided by the area: P= FA A 53-ka woman exerts a force (weight) of 820 newtons.
