• The total current in the given circuit is ___.
• Fault/open-branch scenario — in a two-branch parallel network powered by an ideal source, if resistor R2 opens (becomes an open circuit), what happens to the voltage measured across R1?
• If R1 opens in the given circuit, the total current equals ___.
• The total current in the given circuit equals _____.
• Effect of adding more branches — as additional resistors are connected in parallel to an existing network, how does the total (equivalent) resistance of the circuit change?
• Aging effects — if the resistance value of one branch in a parallel network drifts with age, which electrical quantity in that branch changes as a direct consequence (assuming the supply voltage remains regulated)?
• Parallel circuits — a circuit is said to be parallel between two nodes if more than one independent current path exists between those two points (and all such branches share the same node-to-node voltage).
• Parallel network measurement — if an ideal voltmeter indicates 12 V across the source in a simple parallel circuit, what is the voltage across branch resistor R2?
• Current division insight — in a parallel circuit, the branch having the largest resistance will have which relative current compared with other branches?
• Instrument placement — to measure a branch current, an ammeter is placed in series with that branch; to measure the total current drawn from the supply in a parallel circuit, the ammeter is placed in series with the source lead.
