Electrical /electronic measuring instruments Welcome to your Electrical /electronic measuring instruments 1.What is the voltage measured across a series short? Infinite Zero The value of the source voltage Null 2. What happens to the current in the series circuit if the resistance is doubled? It becomes half its original value It becomes double its original value It becomes zero It becomes infinity 3. When The current in each branch of a parallel circuit is proportional to--- The amount of time the circuit is on for Proportional to the value of the resistors Equal in all branches Proportional to the power in the circuit 4.what happens when the other bulbIf two bulbs are connected in parallel and one bulb blows out? The other bulb blows out as well The other bulb continues to glow with the same brightness The other bulb glows with increased brightness The other bulb stops glowing 5.What is the frequency range of satellite communication method? 4GHz - 6GHz 11GHz -14GHz 5GHz -10GHz 1GHz - 5GHz 6.What is the full form of DVR card Dual Visual Recorder Digital Video Recorder Digital Visual Reader Dual Video Reader 7.Which instrument is used to measure the electrical resistance?
