Find current i, voltages VR₁ and VR₂ in the ciruit below given that the voltage source e = 20 Volts, the resistances R₁ = 100 and R₂ = 300 Ω.

Suppose a 10.0 ohm resistor is connected to an emf source to make a closed circuit. If the source has emf = 15.0 V with an internal resistance r = 0.5 ohms, which of the following correctly compares the voltage drop across the emf source and the attached resistor? O a. Voltage drop across emf source is directly proportional to the external resistor O b. Voltage drop across emf source is greater than external resistor O c. Voltage drop across emf source is less than external resistor O d. Voltage drop is the same for the emf source and the external resistor O e. None of the above

The wires here have zero resistance. Thus, for currents that travel along a wire that has no circuitelement, you can safely omit it and simplify the circuit. After, you can use the Kirchhoff's rules.

a) Determine the total resistance seen from the source in Figure 2. b) Determine the power the source delivers. c) Determine the current through R3. d) Determine the voltage across R6.

In the following figure, the potential of point A is -30 V. Using Kirchoff's voltage law, find the value of V, branch currents and the power dissipated by the 5- ohm resistor. All resistances are in ohms. 4. 5 ww -30 V 12 ww G 4 ww 3. ww 6

The diagram shows an ideal (zero internal resistance) DC source connected to three identical resitances and a switch. In the diagram, the switch is open. If initially, the switch is open, what happens to current I1 and I2 after the switch is closed?

The element shown in figure a) is known as Spinner and has the following relations v - i: v1 = R0i2, v2 = —R0i1. Find an equivalent circuit from the terminals v1, i1 of figure b) that contains only two basic elements connected in parallel, figure c).
