Using the ohm's law formula: for pencil 2 (hb 175cm) with an applied volts of 2v, it shows that the total voltage was decrease to 16v with a current of 01 a and resistance of 16â„¦ compared to pencil 4 (hb 7cm) with an applied volt of 2v, it shows that the total voltage was decreasing to 19v a 01 difference in voltage. Ohm's law 2 in using dc instruments, care must be taken to connect them up with the proper polarity the terminal marked (+) should always be connected to the positive terminal of the power supply and the terminal marked (-) to the negative terminal.
What is ohm's law ohm's law is a law relating the voltage difference between two points, the electric current flowing between them, and the resistance of the path of the current mathematically, the law states that v = ir, where v is the voltage difference, i is the current in amperes, and r is the resistance in ohms. Our object is to confirm ohm's law by analyzing the dependence of the electrical current as a function of voltage and as a function of resistance also, we studied the current flow and voltage in series and parallel. Biography early life georg simon ohm was born into a protestant family in erlangen, brandenburg-bayreuth (then a part of the holy roman empire), son to johann wolfgang ohm, a locksmith and maria elizabeth beck, the daughter of a tailor in erlangen. Ohm's law is the basic electrical engineering law and all other (ee) laws use this in their applications its practical applications are perhaps infinite and extend from small lab circuits to rocket and control systems.
Ohm's law states that the electric current flowing through a conductor is directly proportional to the voltage and inversely proportional to its resistance in a nutshell, the relation between the voltage drop, current and the resistance is as follows where v is the potential drop i is the current and r is the resistance of the conductor. Hypothesis: because i am using copper wire as a resistor, when i increase the length of the wire the resistance should work how resistors in series work.
