PHY101 Assignment 3 Solution Fall 2017

Question # 1

A video game console operates potential difference of 12.00 V as shown in fig. The potential difference supplied by the power receptacle is 120 V AC. A transformer is used to convert one voltage to the other. If the secondary coil of the transformer (the 12.00 V side) has 1200 loops, how many loops does the primary coil have?                                                                  Marks = 10

Question # 2

  1. Is it true or wrong to say that components in series must have the same potential difference across them? Either yes or no explain it. Marks = 5
  2. Is it true or wrong to say that magnetic force vectors on charged particles point in the same direction as the magnetic field? Either yes or no explain it. Marks = 5
  3. What is the electric potential at the location of the test charge in the figure shown below? Marks = 5
