Switching circuit for the expression p ∨ (q ∧ r) corresponds to
Aa switch in parallel with two switches in series
Bthree switches in series
Cthree switches in parallel
Dtwo switches in series with one in parallel
Answer & Solution
Correct answer: A. a switch in parallel with two switches in series
1. AND corresponds to switches in series, OR to switches in parallel.
2. q ∧ r means q and r in series.
3. Then p ∨ (q ∧ r) is p in parallel with the (q-series-r) branch.
