Question 1 For the circuit shown, draw and calculate the currents flowing through each battery and each resistor. What is the total power dissipated by the circuit? 20 volt 10 volt 30 ohm 70 ohm Question 2 An electron is shot into a region of electric field as shown. What direction is the electric force on the electron? -10 cm- U = 4000 m/s + 100 volt Imagine that a magnetic field is also present everywhere between the plates. In which direction should the field point so that the electron can feel zero net force
