Final answer:
The equivalent capacitance Ceq in a circuit where all capacitors are 15μF cannot be determined without knowing how the capacitors are connected; whether in series, parallel, or a combination of both.
Step-by-step explanation:
To find the equivalent capacitance Ceq in a circuit where all capacitors are 15μF, we need to know how the capacitors are connected. Capacitors can be connected in series or in parallel. When connected in series, the reciprocal of the equivalent capacitance is the sum of the reciprocals of the individual capacitances: 1/Ceq = 1/C1 + 1/C2 + ... + 1/Cn.
For capacitors in parallel, the equivalent capacitance is the sum of their capacitances: Ceq = C1 + C2 + ... + Cn. Since the problem statement does not provide the connection layout of the capacitors, we cannot calculate the equivalent capacitance without further information.
To find the equivalent capacitance (Ceq) of the circuit, we need to determine how the capacitors are connected. If the capacitors are in series, their reciprocals add up to the reciprocal of Ceq. If they are in parallel, their capacitances add up to Ceq. In this case, since all capacitors are 15μF, and they are connected in parallel, the equivalent capacitance (Ceq) would be equal to the sum of their individual capacitances, which is 15μF + 15μF + 15μF = 45μF.
