Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. 1 … WebbThe answer is no. The vertical test whether the two resistors are in series or not, is remember that they need to have the same current flowing through them. That's the definition of series. So, I would imagine a small current flowing over here and see if that entire current flows here. If it does, they are in series. If not, they're not in series. biology pittsburgh

Webb10 apr. 2024 · Hint: Here we have a circuit with three capacitors having capacitance $1\mu F$ each. The potential at a particular point is given and we have to find the potential at another point. For that, we have to find whether the capacitors are in series or parallel combination and using equivalent circuits we have to find the potential. WebbV1 - R1*I - V2 - R2*I = 0. Solving for current: I = (V1 - V2) / (R1 + R2) And so the potential difference across is R1 is V = R1*I = R1* (V1 - V2) / (R1 + R2). So the potential at a would be V1 - R1* (V1 - V2) / (R1 + R2). homework-and-exercises. electric-circuits. Share. Cite.
