Show me ur works
For the circuit below Delta V = 18. 0 volts C1 = 10. 0 mu F, C2 = 12. 0 mu F, and C3 = 4. 70mu F. Find the voltage and charge on each capacitor. Pi. In the circuit at right the switch is initially open. We want to measure the potential across the unknown battery but our voltmeter is broken. We know the resistance of resistor R-, to good precision from previous measurements. We do not know the resistance of R2 to sufficient precision to properly measure the potential across the battery. So first we'll measure the resistance of R2. What is the potential difference across R2 when the switch is open?. With the switch open the ammeter reads 1. 00 a. What is the resistance of resistor R2 to an appropriate precision?. When the switch is closed the ammeter reads 1. 57 a. What is the potential difference across resistor R2 now? What is the potential difference across the unknown battery?Explanation / Answer
the C1 and C2 capacitors are in parallel therefore
C = C1 + C2
the capacitor C and C3 are in series therefore
1/C' = 1/C + 1/C3
the charge on capacitor C and C3 is same as they are in series therefore
Q = C' x V
V = 18.0 V
let V1 and V2 be the voltage on capacitor C1 and C2 therefore
V1 = (Q/C1)
and V2 = (Q/C2)
