decrease the resistance D. disconnect the circuit 相关知识点: 试题来源: 解析 C。解析:根据欧姆定律(Ohm's law),电流(current)等于电压(voltage)除以电阻(resistance),即I = V/R。要增大电流,可以减小电阻。A选项增大电阻会使电流减小;B选项减小电压会使电流减小;D选项断开电路则没有电流通过。
1英语翻译A voltmeter is always placed across(in parallel) the circuit or component to be measured.When measuring current,the circuit must be opened and the meter inserted in series with the circuit or component to be measured.When measuring the resistance of a component in a circuit,the voltage...
In a circuit, if the current decreases and the resistance remains constant, what happens to the voltage? A. It increases. B. It decreases. C. It remains the same. 相关知识点: 试题来源: 解析 B。根据欧姆定律,电阻不变,电流减小,电压也会减小。
May i ask if we are increasing the load in a circuit,i believe the current also increases.Does that increase in current caused by the additional power added to the circuit or due to the addition of the extra load in parallel which reduces the overall resistance which in turn increases the...
The circuit with a current divider is provided for synchronized inverters operating in parallel and which together supply a charge with current. The current divider is composed of a transformer (1) comprising a multiple branch core formed by at least as many branches (11, 12, 13) magnetically ...
