解析 答案:Ohm's Law is fundamental in electrical engineering as it relates the voltage (V), current (I), and resistance (R) in a simple electrical circuit, expressed as V = IR, allowing for calculations of these quantities.反馈 收藏 ...
Example: Using Ohm’s Law to Calculate Current in a Circuit The best way to learn how to use Ohm’s law is by looking at some examples. Below is a very simple circuit with a battery and aresistor. The battery is a 12-volt battery, and the resistance of the resistor is 600 Ohms. ...
In the circuit of Figure 1, we can immediately apply Ohm’s Law to eachresistorto find its current because we know the voltage across each resistor (9 V) and its resistance. IR1=VR1R1=9V10kΩ=0.9mAIR1=VR1R1=9V10kΩ=0.9mA

The 'conductor' mentioned by Ohm's law is a circuit element across which the voltage is measured. Resistors are conductors that slow down the passage of electric charge. A resistor with a high value of resistance, say above 10 megaohms, is a poor conductor, while a resistor with a low ...
Ohm's law — voltage equals current multiplied by resistance — dates back to 1827 and has been taught to physics students for generations. Until recently it was widely accepted that quantum effects would cause this familiar law to break down at the nanoscale, but Michelle Simmons and co-worker...
