1. 1. COPER INTRODUCTION THEORICAL IN PHSICS A. SERIES CIRCUIT PARALLEL CIRCUIT PICTURE AND ANIMATION SERIES AND PARALLEL CIRCUIT
2. 2. A. INTRODUCTION INTRODUCTION Circuit OfPHSICS THEORICAL IN Electrical Have Two Kind it is : A. SERIES CIRCUIT PARALLEL CIRCUIT PICTURE AND ANIMATION SERIES PARALLEL
3. 3. EXAMPLE IN OUR LIFE INTRODUCTION THEORICAL IN PHSICS A. SERIES CIRCUIT PARALLEL CIRCUIT PICTURE AND ANIMATION BRIDGES CONNECTED IN SERIES If any one of the bridges breaks, can the runners still reach the other side?
4. 4. INTRODUCTION THEORICAL IN PHSICS A. SERIES CIRCUIT PARALLEL CIRCUIT PICTURE AND ANIMATION BRIDGES CONNECTED IN PARALLEL If any one of the bridges breaks, can the runners still reach the other side?
5. 5. THEORICAL IN PHYSICS INTRODUCTION THEORICAL IN PHSICS A. SERIES CIRCUIT PARALLEL CIRCUIT PICTURE AND ANIMATION Look at the picture? which there either be series or parallel?
6. 6. A. SERIES CIRCUIT INTRODUCTION THEORICAL IN PHSICS A. SERIES CIRCUIT PARALLEL CIRCUIT What happen if one bulb is PICTURE AND ANIMATION removed? When one bulb is removed from its socked, the other bulbs in series be turn off all.  A series circuit is a circuit in which resistors are arranged in a chain, so the current has only one path to take. The current is the same through each resistor. The total resistance of the circuit is found by simply adding up the resistance values of the individual resistors:  equivalent resistance of resistors in series : R = R1 + R2 + R3 + ...  Use Ohm’s Law to find current using resistance and voltage I= V/R
7. 7. INTRODUCTION Information About Current, Resistor THEORICAL IN PHSICS And Voltage In Series Circuit A. SERIES CIRCUIT PARALLEL CIRCUIT  Current is the same at all points PICTURE AND ANIMATION  Voltage is reduced by each resistance – voltage drop  Total resistance will go up because all of the current must go through each resistor
8. 8. B. PARALLEL CIRCUIT  The voltage across each resistor in parallel is the THEORICAL IN PHSICS same. A. SERIES CIRCUIT  The total resistance of a PARALLEL CIRCUIT set of resistors in parallel What happen, if one bulb is found by adding up the PICTURE AND ANIMATION is removed? reciprocals of the resistance values, and then taking the reciprocal of the total:  equivalent resistance of resistors in parallel: 1 / R = When one bulb is removed 1 / R1 + 1 / R2 + 1 / R3 +... from its socket, the other bulbs in the parallel branches remain lit. INTRODUCTION
9. 9. INTRODUCTION Information About Current, Resistor THEORICAL IN PHSICS And Voltage In Parallel Circuit A. SERIES CIRCUIT PARALLEL CIRCUIT  Current flows into a branching point, the same PICTURE AND ANIMATION total current must flow out again  Current depends on resistance in each branch  Voltage is the same across each branch – because each branch is on the same wire  Calculate current in each branch based on resistance in each branch by using Ohm’s Law
