The capacitor in the circuit shown below is initially uncharged. The switch is closed at t=0 s. AV battery = 30 V, C = 3.0 F, and R = 2.0 Q. What is the current in the circuit at t - 3.1 s, in Ampere? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

What is the current read by the ammeter in the circuit below? Let R1 = 1 kiloohm, R2 = 2 kiloohm, R3 = 3 kiloohm, and the emf of the ideal source is 5 volts. Input R1, R2, and R3 for resistors R1. R2, and R3 respectively. Input E for the emf E. Use context clues to figure out if you need to input a numerical value, variable, word, etc. All numerical answers should be in three significant figures. R| R2 R3 First we calculate the current across each resistor. From Ohm's law, we arrive at a general formula for current: Plugging in values, the current across the resistor R1 is equal to: (Please note that the current is milliamperes) Similarly the current across R2 is: 12= mA And the current across R3 is: 13 = mA The current read by the ammeter is the sum of the currents across each resistor: 1=h+/2 +13 |= Alternatively, we can solve for the current across the ammeter by first calculating the equivalent resistance and then applying Ohm's law. The equivalent resistance of the three resistors…

Two resistors are included in the circuit shown. R1= 280 ohms R2= 120 ohms and delta V= 13 volts Identify the type of circuit. What is the total (equivalent) resistance of the circuit? What is the current flowing into and out of the voltage source? The drops in voltage across the resistors are: delta V1=? and delta V2=? The current flowing through each resistor is: I1=? and I2= ?

Consider the following circuit diagram. The potential difference across the battery is 40.0 volts, and it supplies a current of 5.00 amperes to the circuit. There is a current of of 2.70 amperes flowing through R1. Resistor R2 has a resistance of 5.50 ohms. What is the resistance of R3? Answer in ohms to two decimal places, but do not include units in your answer.

A 0.7-F capacitor is connected in series with a 9-ohm resistor. If the connection is energized from an 11-V DC source, determine the voltage (in volts) across the resistor at t = 2.75 ms. The initial charge is 175 mC. Express your answers accurate to four decimal places. No need to put the units. Do not put spaces.
