The solution for the new circuit in the right-hand figure above is thus R = 10 Ω and I = (E/RT=) 1/10 A = 0.1 A. 8. We want to know the voltages UAand UBat points A and B, respectively, in the figure below; the resistor R = 10 Ω. We use the superposition theorem, since we have both a current source and a voltage source. Since the value of frequency and inductor are known, so firstly calculate the value of inductive reactance X L: X L = 2πfL ohms. Step 2. From the value of X L and R, calculate the total impedance of the circuit which is given by. Step 3. Calculate the total phase angle for the circuit θ = tan – 1 (X L / R). Step 4. 1. Series Circuit Calculator-In a series circuit connection, the number of electrical elements or components are connected in series or sequential form. For example, the given circuit is said to be series circuit, when electronics components (such as resistance R1, R2 and R3) are connected in a single path with connected voltage source (Vs.

Consider a portion of circuit that has several resistors in series, like the circuit at right. Suppose we want to find the voltage across R 2. R 1 R 2 R 3 + – V S + v R1 – – + v R2 i S – v R3 + We could start by finding the current, which would be equal to the source voltage divided by the equivalent resistance of the string. For the. SOLUTIONS: PROBLEM SET 3 ELECTRIC CURRENT and DIRECT CURRENT CIRCUITS PART A: CONCEPTUAL QUESTIONS A. If we connect them in series, R eq = 300Ω. If we connect them in parallel, R eq = 30 Ω Therefore, in order to obtain a 150 Ω resistance, we have to connect the resistors in parallel and in series Connecting two in parallel: R eq1 = 50 Ω. 12.2 Simple AC circuits Before examining the driven RLC circuit, let’s first consider the simple cases where only one circuit element (a resistor, an inductor or a capacitor) is connected to a sinusoidal voltage source. 12.2.1 Purely Resistive load Consider a purely resistive circuit with a resistor connected to an AC generator, as shown.
