Voltage - Current relationship in a DC circuit

ABSTRACT         Ohms virtue and Kirchhoffs rules is fundamental for the understanding of dc galvanising circuit. This experiment proves and manoeuvre how these rules can be applied to so simple dc circuits. INTRODUCTION         In the theory of Ohms Law, emf is simply proportional to accredited as illustrated in the proportionality, V=RI. As shown in this relation, V represent potential difference which is the voltage difference across the two ends of a galvanisingal theatre director and between which an electric incumbent, I, will flow. The constant, R, is called the conductors confrontation. Thus by the Ohms Law, unrivalled can determine the resistance R in a DC circuit without measuring stick it directly provided that the rest variable V and I is known.         A resistor is a piece of electric conductor which obeys Ohms Law and has been designed to realise a specific value for its resistance. As an extension of th e Ohms Law, two more relationship can be drawn for electric circuits containing resistors machine-accessible in serial publication or/and repeat. For resistors connected in series, the total of their resistance is, RTOTAL=R1+R2+ ..... +Rn . And for resistors connected in parallel, 1/RTOTAL==1/R1+1/R2+ ..... +1/Rn . mixed dc circuit involving a combination of parallel and series resistors can be analyzed to find the received and voltage at each point of the circuit apply 2 basic rules formulated by Kirchhoff.

1) The algebraic sum of current at both branch point in a circuit is zero. 2) The algebraic sum of potential difference, V, almost any closed loop in a circuit is zero. These rules and equations provided by the O! hms law and the Kirchhoff rule can be by experiment tested with the apparatus available in the lab observational METHOD         The apparatus utilize in the experiment includes a Voltmeter, an Ammeter, some connecting wires and a series of resistors and light...
