The voltage at both ends of the wire is 10V, and the resistance of the wire is ignored. Calculate the current in the wire
Your wire always has resistance. If the resistance is ignored, it is a pure theory, then the current of the wire is infinite
If the voltage at both ends of the resistance becomes 8V, what is the current through the resistance? When the voltage at both ends of the resistance is 0, what is the resistance of the conductor? What is the current?
The first resistance is 20 ohm
Resistance equals voltage divided by current. LZ seems to lack necessary conditions. Anyway, I won't
The current in a section of conductor is proportional to the voltage at both ends of the conductor______ It's related to the resistance of this conductor______ Relationship
According to Ohm's law, the current in a conductor is directly proportional to the voltage at both ends of the conductor and inversely proportional to the resistance of the conductor
When the voltage at both ends of a conductor is 12V, the current passing through it is 0.2A, and its resistance is______ Ω; when the voltage at both ends is 6V, its resistance is______ Ω; when the voltage at both ends is 0V, its resistance is______ Ω, the current through the conductor is______ A.
According to Ohm's Law: r = UI = 12v0.2a = 60 Ω; because the conductor resistance is independent of the voltage at both ends of the conductor, the conductor resistance remains unchanged at 6V and 0V, so it is 60 Ω; according to Ohm's law, when the voltage at both ends of the conductor is 0, the current through the conductor is 0A. So the answer is: 60; 60; 60; 0
