- p. No - EXP. Name: Resistance connection. EXPAIM: to know the connection resistance types and to solve the electric circuits haves many resistance. Theory: The electrical resistance is the resistant of the conductor to the current have a constant value. Three kinds of resistance connection: 1-Series connection:- In a series circuit,(fig ),the current is the same through all of the circuit elements. The total resistance R1 R/+R2+Ri. By ohms law,the current "I" is 1-E/R: Applying kirchoffs voltage law around closed loop of fig( 1) we find: EVI+V2+V3 Where Vi-IR1 V IR2 V IR3 I is the same throughout the circuit Vi=R/E/R V2=R2E/R/ V=R3E/R Page LEC DR.

- The arc length voltage characteristic of a DC arc is given by the equation V=24+4L where 'V' is the arc voltage in volts and L' is the length in mm. The static volt-ampere characteristic of the power source is approximated by a straight line with no load voltage of 80V and the short circuit current of 600A. Then the optimum arc length is (mm).arrow_forwardWhat are the three types of opposition to current flow that impedance represents?arrow_forwardWi W2 W3 The shown schema for measurement of active power in three phase systems is: Select one: 1.
