Two batteries and a resistor are connected as shown. 1 = 20 V, 2 = 8.0 V, and R = 2.0 02. What is the current through the resistor, in Amperes? 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. €2 ww

Q.6. R1= 50 ohm, R2= 25ohm, V1=30V. Find the current through R1 and R2 and the current leaving the voltage source. V. R, ŽIRI Ra

A battery is connected to three resistances 5 ohm, 4 ohm & 3 ohm which are connected in series.  a. Find the effective resistance of the circuit? b. Suppose 5 ohm resistor has a voltage of 12 V across it. What is the value of current through each of the resistors? c. What is the value of the battery voltage?

If you examine your smartphone battery, you will likely see two numbers: the battery's "capacity" labeled in mAh (milliamps x hours or milliamp-hours), and the battery's voltage or potential difference in V (volts). 1. What physical quantity is the battery's "capacity" measuring? Explain how you can tell. This answer has not been graded yet. 2. Suppose your phone's battery has a capacity of 2500 mAh and a potential difference of 3.7 V. What is the amount of charge, in C (coulombs), that is stored in your smartphone battery when it's fully charged? Charge = 3. Smartphone chargers are usually labeled with their current output in A (amps). Suppose your charger delivers a current of 1.1 A. If your phone's battery is completely drained, how long will it take to fully charge the battery using your charger? Charging time = hours 4. Smartphones are advertised with a certain amount of "talk time", i.e., how long the phone's battery will last if you are making a call. If your phone is advertised…
