Assume no resistance in  and .
(b) If \(R_{7}\) increases, the potential difference between  and ___________________.
Assume  and \(\varepsilon\)  have resistance.
(c) If R7 increases, the voltage drop across \(R_{4}\)  __________________.

(d) If R2 decreases, the current through \(R_{1}\)__________________.

(e) If R2 decreases, the current through \(R_{6}\)__________________.

(f) If R2 decreases, the current through \(R_{3}\)_________________.

(g) If R5 increases, the voltage drop across \(R_{2}\)________________.

(h) If R5 increases, the voltage drop across \(R_{4}\)________________.
