Question

a) A 31 k\Omega resistor and a 44 k\Omega resistor are connected in parallel to a DC power supply. Calculate the total resistance. b) Two resistors are connected to a 117.5 V power supply. If a total current of 5.45 mA is drawn from the power supply, determine the total resistance of the circuit. c) A 3.76 mH inductor, 7.96 \mu F capacitor and 1.13 \Omega resistor are connected in series to an AC power source with an rms voltage of 6.04 V. What frequency produces the maximum current? d) A particle (whose charge is -3.14 nC) is travelling with a velocity of 6.88 \times 10^3 m/s up the page, perpendicularly to a magnetic field. If the resulting force was 8.92 \times 10^{-12} N, directed out of the page, determine the magnetic field.

          a)
A 31 k\Omega resistor and a 44 k\Omega resistor are connected in parallel to a DC power supply. Calculate the total resistance.
b)
Two resistors are connected to a 117.5 V power supply. If a total current of 5.45 mA is drawn from the power supply,
determine the total resistance of the circuit.
c)
A 3.76 mH inductor, 7.96 \mu F capacitor and 1.13 \Omega resistor are connected in series to an AC power source with an rms
voltage of 6.04 V. What frequency produces the maximum current?
d)
A particle (whose charge is -3.14 nC) is travelling with a velocity of 6.88 \times 10^3 m/s up the page, perpendicularly to a
magnetic field. If the resulting force was 8.92 \times 10^{-12} N, directed out of the page, determine the magnetic field.

d)
A particle (whose charge is -3.14 nC) is travelling with a velocity of 6.88 ×10^3 m/s up the page, perpendicularly to a
magnetic field. If the resulting force was 8.92 ×10^-12 N, directed out of the page, determine the magnetic field.
