====== Electric Fields I: Field Mapping ====== ---- ==== Common area ==== * Rulers * Extra spare parts, especially the following: * Multimeters * Binder clips with small alligator clip wire (both types) * Function generator | {{:phylabs:lab_courses:phys-120_130-wiki-home:winter-experiments:electric-fields-i_field-mapping:field_mapping_common_area.png?direct&400|}} | ==== Individual station ==== * Large metal lunch tray * Smaller plastic frame box * Field mapping coordinate lines insert * Binder clip with small alligator clip wire (without resistor) * Binder clip with small alligator clip wire (with resistor) * Field mapping shapes: * Round cookie tin * Bent U-shape * Long bars (2) * Round cylinders (2) * BK 3011B function generator (Modified or unmodified version is OK here) * BNC to double-banana adapter * 2 black and 1 red patch cable * Multimeter * Red single-prong multimeter probe * Double-prone multimeter probe | {{:phylabs:lab_courses:phys-120_130-wiki-home:winter-experiments:electric-fields-i_field-mapping:field_mapping_individual.png?direct&400|}} | ==== Setup notes ==== On the function generators... * ...make sure that **all knobs are turned fully counter-clockwise (minimum/off) except for amplitude (which should be fully clockwise (maximum)**. * ...set the frequency to a few thousand kHz and amplitude to maximum, which should correspond to about 7-10 V, peak-to-peak as measured on the AC voltage setting on the multimeter.
