1. In a particular television tube, the beam current is 60.0 MuA. How long does it take for 3.75 x 10^14 electrons to strike the screen?
2. A stereo with a resistance of 65 ohms is connected across a potential difference of 120 V. What is the current in this device?
3. The current in a microwave oven is 6.25 A. If the resistance of the oven's circuitry is 17.6 ohms, what is the potential difference across the oven?© BrainMass Inc. brainmass.com March 4, 2021, 5:53 pm ad1c9bdddf
1. In a particular television tube, the beam current is 60.0 Mu A How long does it take for 3.75 x 10^14 electrons to strike the screen?
Current= 60 Mu A =60x10^(-6) A
A current of 60 Mu A involves the transfer of charge of 60x10^(-6) Coulombs per second= 0.00006 Coulombs/sec
This solution provides a detailed, step by step explanation of the given physics problems.
