A battery with E = 7.60 V and no internal resistance supplies current to the circuit shown in the figure below. When the double-throw switch S is open as shown in the figure, the current in the battery is 1.00 mA. When the switch is closed in position a, the current in the battery is 1.16 mA. When the switch is closed in position b, the current in the battery is 1.98 mA. R R R (a) Find the resistance R,. (b) Find the resistance R2. (c) Find the resistance R3.

In the figure, & = 134 V, R₁ = 8.500, R₂ = 17.602, R3 = 26.4 02, and L = 2.14 H. Immediately after switch S is closed, what are (a) i₁ and (b) i2? (Let currents in the indicated directions have positive values and currents in the opposite directions have negative values.) A long time later, what are (c) i₁ and (d) i₂? The switch is then reopened. Just then, what are (e) i and (f) i2? A long time later, what are (g) i₁ and (h) i₂?

PART (1) Assume capacitor is fully charged when switch is at position 'a' for about 10 minutes. The switch is changed to position 'b' at t= 0. What is the current in the circuit immediately after the switch is closed? Assume after some time, the current in the circuit is 80.0 mA when the switch is at position 'b'. Can you find, what will be that time? 9.0 V 부 Paragraph a itur b 1.0 με PART (II) Assume a magnetic field of 5.2 T present inside the cyclotron. An electron enters the cyclotron with speed of 2.0 x 107 m/s. What is the radius of the electron's orbit just before they exit from the cyclotron. BI U A/ 10 Ω E✓ E GO + v
