STEP BY STEP SOLUTION, CLEAR WRITTING AND INFORMATION AND ALSO NO SCRUBBLE

1. How much current flows through resistor 1? It is known that I = 5A, R1 = R2 = 2R3 = 2R4 = 40. 2. In the circuit below, if Emf is 12 Volts, R1 = 2k, R2 = 3 150.. and R3 = 4141, calculate the potential difference between points C and D? 3. In the circuit below, it is known that C1 = luF and the other three capacitors have the same capacitance where each has a capacitance of 2C1. If the VEIUE of C1 in capacitor 1 is 30 HQ, calculate is the potential difference between point A and point B? 01 Ca ca :2. In the circuit below, each capacitor has capacitance of 10 ME, and connected to 10 V battery. What is the value of the charge on capacitor 2 5. The gure below shows the electric potential ofa copper wire owing from a high potential V5 = 12pV at x = 0 to point of zero potential at 3%: 3m. calculate the current in the wire? 9; . V (IN)
